@ MonsieurT Both of those problems are issues that have been around for a while, I submitted a bug report a couple of months ago. Anytime a Python REPL is copied from one team to another, it’s changed to a Blank or Bash REPL.
I’m guessing the “multiple” files you’re talking about are the hidden files/folders (.config, venv, .replit, replit.nix) that are showing up? I submitted a bug for that as well. I just told my students to ignore them.
By default, copying a project over from a team sets the language of the project to be a blank repl, or Nix. This enables better scalability and customization. The cloned repl will behave the same as the original one, so no worries on that.
